If your soldering skills arnt up to much, you won't be able to jtag. It's a hack for people who are a bit more technically minded.
If you still want to proceed, then you can buy a nand-x kit. There are suppliers who ship internationally.
Knowing the history behind your request, in my opinion, unless you want to get into the homebrew scene, I'd just get a new / second hand xbox.
Jtagging will get your drive key, which is what your after, but you've got to look at the cost of retrieving the key, soldering, time and effort.
